Answer:
x=-2
y= 8
Step-by-step explanation:
Given data
10x – 2y = -36-----------1
7x – 2y = -30--------------2
-Subtract to eliminate y
3x-0= -6
3x= -6
x= -6/3
x= -2
Put x= -2 in
7(-2)– 2y = -30
-14-2y=-30
-14+30=2y
16=2y
y= 16/2
y= 8
Wait it says ur in high school so u can't be over 30. that isn't possible. So what's the problem here? not good at math.
The equation of this line in slope intercept form is y= 3/7x
Subtract 7a from both sides giving you 10=-5a and divide everything by 5. This gives you a=-2
